STONE-GHANNELING MACHNE.

Application filed July 26, 1927. Serial No. 208,626.

The present invention relates to a stone channeling machine, and has forits prime object to provide a machine of this nature which isexceedingly simple in its construe tion, strong and durable, inexpensiveto manufacture, thoroughly etlicient and reliable in use in operation,and otherwise well adapted to the purpose for which it is designed.

A further and -important object of the invention resides in theprovision of a ma chine of this nature with a plurality of stone cuttingtools grouped in a compact and convenient manner, and operated by asingle shaft, and Iincorporates water cooling means for properassociation with the tool.

With the above and numerous other objects in view as will appear as thedescription proceeds, the invention resides in certain novel features ofconstruction, and in the combination and arrangement of parts as will behereinafter more fully described and claimed.

In the drawing Figure l is a side elevation of a machine embodying thefeatures of my invention,

F ig. 2 is a vertical section therethrough,

Fig. 8 is a transverse horizontal section taken substantially on theline 3-3 of Fig. 2,

Fig. i is a horizontal transverse section taken substantially on theline lwll of Fig. 2, and

Fig. 5 is a top plan view of the machine.

Referring to the drawing in detail, it will be seen that the numeral 5denotes an elongated casing of a flat-like formation, which has anenlarged portion 6 a slight distance from the upper end thereof. A.partition 7 entends longitudinally and centrally of the casing anddivides the same into two compartments. This partition terminates at theenlarged portion 6.

A bearing block 9 yis mounted in the upper end of the casing, and in thepresent instance has four openings or bores l0, the number of thesebores, is not of the essence of the invent-ion. Anti-friction bearingsare provided lin the enlarged portion 6 as is shown at 1l.

A plurality of shafts l2 are `iournaled in the bores i and bearings l1and entend longitudinally thru the two compartments of the casing, andare journaled in a bearing block structure 11i in the bottom of thecasing. The lower ends of these shafts are provided with transverseopenings l and longitudinally extending openings 16 which pass throughthe enlarged extremities 17.

he openings 16 provide sockets for receiving shrinks 18 of tools 19which have bores 20 kto communicate at one end with the openings 16 andmerge at their ends into lateral openings 20.

The bearing blocks lt are provided with inverted ii-shaped conduits orchannels 2l, the lower extremities of which are adapted to communicateor register with the openings l5. rllhe pipes 22 lead upwardly from thetops of the T-shaped openings 2l and have elbows 23 at their upper endswith entensions through openings in the casing as Iindicated at 24.These pipes 22 will be connected with a suitable source of water.

A drive shaft 26 is engaged with one of the shafts l2, preferably one ofthe center shafts l2. All the shafts 12 at their upper ends, rave fixedthereto gears 27, which are in mesh with one another, so that theturning of the drive shaft 26 will cause the rotation of all the shaftsl2, together, adjacent shafts turning in opposite directions. Thusthectools will rotate and adjacent tools will be rotating in oppositedirections.

This unit is used for channeling and slotting stones, and can be widenedout to contain any number of cutters. Suitable means may be used forforcing the apparatus against the stone. rThe cutter starts 0n top ofthe stone, and goes down through the depth desired to form the channel,and then may be raised up and moved over the width of the cutter andthen it cuts down another slot, and thus a completed channel may beformed as may be desired.

It will be seen that the machine is compact and convenient ,inconstruction, and is strong and durable. rlhe present embodiment of theinvention has been disclosed in detail merely by way of example, sincein act-ual practice it attains the features of advantage enumera-ted asdesirable lin the statement of the invention and the above description.l

lt is apparent that changes in the details of construction, and in thecombination and arrangement of parts may be resorted to withoutdeparting from the spirit or scope of the invention as hereinafterclaimed, or sacrificing any of its advantages.

Having thus described my invention, what I claim as new lis l. Anapparatus of the class described comprising a casing, a plurality ofshafts journaled in the casing longitudinally thereof and in spacedrelation to each other, the lower ends of the shafts projecting beyondthe lower end of the casing, said lower ends of the shafts being formedwith longitudinal bores merging into transverse openings inwardly of thecasing, the lower portions of the bores forming sockets, tools havingshanks fitting 4into the sockets, said shanks being hollow and merginginto lateral openings exteriorly of the sockets, pipes extendinglongitudinally of the casing between the shafts, and means in the casingcommunicating each pipe with the transverse openings in the shafts nextadjacent, so that each pipe casing being formed with bores having attheir |inner ends transverse openings, tools having hollow Shanksprojecting into the bores and iormed with openings eXterioi-ly of thebores, a pipe in the casing between the shafts, and means forcommunicating the pipe with the transverse openings of the shafts toform a common supply therefor.

ln testimony whereof I aliix my signature.
